On my Macbook Air running OS X 10.8 Mountain Lion, when I click on the Time Machine backup menubar item, I see the option to browse other backup disks. That’s a pretty cool option, if I need to switch between different disks to backup my Mac; maybe to make a secondary backup for redundancy.

In Mavericks, the Time Machine menu bar icon doesn’t have this option any more, instead only showing Stop This Backup when backing up (or Back Up Now when it isn’t), Enter Time Machine, and Open Time Machine Preferences. If you’re wondering where the option to browse other backup disks has gone, you’re not alone.

The Option key is a powerful ally in the transition from new, beginner user of OS X to the power user that you want to be. There are a ton of hidden features in the Finder alone that are hidden behind the underrated and unassuming Option key. There are Option key tricks for the OS X Menu Bar, for apps in the iWork suite, in Safari, and a few more random ones to boot.

So, sit back, relax, and get ready to hit that Option key a whole bunch of times in a row.

What fun the Option key is in OS X, right? Adding it to clicks and keystrokes makes many features accessible that would otherwise be hidden. We’ve spent the last few days talking about how to maximize the Option key in your power-user Mac workflow, in the Finder, the Menu Bar, and in iWork apps.

Now, we’re going to head over to Apple’s built-in browser, Safari, and show you how the Option key can make your Safari life just that bit better.
